"Vorrichtung zum kontinuierlichen Dämpfen von Stapelfasern" Zusatz zu Patentanmeldung P 2o o8 o79.9 ; · "Device for the continuous steaming of staple fibers" addendum to patent application P 2o o8 o79.9 ; ·
Die Erfindung bezieht sich auf eine Vorrichtung zum kontinuierlichen Dämpfen von Stapelfasern insbesondere Schrumpfen von Chemiefasern, vorzugsweise Pplvacrylnitril-Fasern, die aus einem von einem endlosen, perforierten Transportband, durchlaufenen Dämpfergehäuse mit einem Aufheizteil, mit einem Verweilteil mit einer ruhigen, absolut luftfreien Dampfatmosphäre und einer im Bereich des Auslaufs des Transportbandes aus dem Gehäuse angeordneten, den Dampf aus den Fasern absaugenden Dampfabsaugvorrichtung besteht, insbesondere nach Patentanmeldung P 2o o8 Ο79.9.The invention relates to a device for continuously steaming staple fibers, in particular shrinking Man-made fibers, preferably Pplvacrylonitril fibers, which from one passed through by an endless, perforated conveyor belt Damper housing with a heating part, with a dwell part with a calm, absolutely air-free steam atmosphere and a arranged in the area of the outlet of the conveyor belt from the housing, the steam sucking off the fibers of the steam suction device exists, in particular according to patent application P 2o o8 Ο79.9.
Mit dieser Vorrichtung löst die Erfindung nach der Hauptanmeldung die ihr zugrunde liegende Aufgabe, einen Siebbanddämpfer zu entwickeln, in dem Chemiefasern bis auf einen äußerst geringen Restschrumpfwert mittels Sattdampf ausgeschrumpft werden können.The invention according to the main application is achieved with this device the underlying task of developing a filter belt damper in which man-made fibers except for an extremely small one Residual shrinkage value can be shrunk by means of saturated steam.
Die zu schrumpfenden Stapelfasern liegen in wirrer Lage in Form eines Vlieses auf dem.Transportband auf und ziehen sich infolge der Einwirkung des Dampfes in sich zusammen. Als Transportband für derartige Dämpfer kommt im allgemeinen ein Siebgewebeband aus VA-Stahl zur Anwendung, das aus einem Geflecht von dünnen Drähten besteht. Derartige Bänder haben sich im Gegensatz zu den Gliederbändern, die durch den häufigen Biegungswechsel einem hohen Verschleiß ausgesetzt sind, insofern bewährt, als von einem Verschleiß infolge von mechanischen Beanspruchungen beiThe staple fibers to be shrunk lie in a tangled position a fleece on the conveyor belt and pull themselves as a result the action of the steam in itself. A mesh belt is generally used as the conveyor belt for such dampers made of VA steel for the application, which consists of a braid of thin Wires. In contrast to the articulated belts, these types of ligaments have changed due to the frequent change of bend are exposed to high wear, in so far as they have been tried and tested wear due to mechanical stress

einem Siebgewebeband nicht gesprochen werden kann. Nachteilig ist jedoch die nicht zu vermeidende Erscheinung, daß sich einzelne Fasern zwischen den Drähten, insbesondere an deren Kreuzungspunkten, verklemmen und somit das Siebband auf die Dauer derart verschmutzen, daß eine optimale Durchdringung des Vlieses mit Dampf innerhalb der vorausgegebenen Zeit nicht mehr möglich ist.a sieve mesh belt cannot be spoken of. The disadvantage, however, is the unavoidable phenomenon that individual Fibers between the wires, especially at their crossing points, jam and thus the screen belt on the Soiling for a long time in such a way that optimal penetration of the fleece with steam no longer occurs within the given time is possible.
Der Erfindung liegt die Aufgabe zugrunde, die anfangs genannte Vorrichtung insbesondere nach der Patentanmeldung P 2o 08 o79.9 derart weiter zu entwickeln, daß eine Verschmutzung des endlosen Transportbandes durch die Fasern nicht mehr möglich ist und somit auch über eine längere Zeit eine stets gleichbleibende Einwirkung des Dampfes über die ganze Dicke des Vlieses möglich gemacht ist.The invention is based on the object of the initially mentioned device in particular according to the patent application P 2o 08 o79.9 to develop further in such a way that contamination of the endless conveyor belt by the fibers is no longer possible and thus made a constant effect of the steam over the entire thickness of the fleece possible even over a longer period of time is.
Erfindungsgemäß besteht die Lösung darin, daß anstelle des bisher verwandten Siebgewebebandes das. endlose Transportband ein fugenloses, mit Perforierungen versehenes Stahlband oder aus einem dafür geeigneten Kunststoff besteht. Ein solches fugenloses Band mit eingestanzten Perforierungen weist eine hohe Lebensdauer auf. Außerdem ist eine Verschmutzung desselben durch an dem Band klemmende'Fasern nicht möglich, vielmehr kann es durch seine glatte Oberfläche als selbstreinigend bezeichnet werden.According to the invention, the solution is that instead of the previously used screen fabric belt, the endless conveyor belt seamless, perforated steel strip or a suitable plastic. Such a jointless one Tape with punched perforations has a long service life. In addition, pollution of the same is due to Fibers sticking to the tape are not possible, rather it can be described as self-cleaning due to its smooth surface.
In der Zeichnung ist lediglich in perspektivischer Darstellung ein Ausschnitt aus einem Stahlband gezeichnet, in dem einzelne Perforationslöcher eingestanzt sind.In the drawing, a section of a steel strip is only drawn in perspective, in which individual Perforation holes are punched.
